What is a Legionella Risk Assessment?
A legionella risk assessment survey is a detailed inspection and review of your water systems, including:
- Hot and cold water systems
- Cold water storage tanks and calorifiers
- Showers, taps and outlets
- Pipework, dead legs and infrequently used areas
- Aerosol-generating equipment (where applicable)
The assessment identifies conditions where legionella bacteria may grow and spread, particularly in water temperatures between 20–45°C and where stagnation or biofilm is present.
You will receive a comprehensive legionella report including:
- Risk matrix, ratings and photographic evidence
- Asset register & temperature profiles
- Clear, prioritised remedial actions
- Colour schematic drawings
- A framework for ongoing water hygiene monitoring and control
Why is a Legionella Risk Assessment Required?
Under UK law, dutyholders must carry out a “suitable and sufficient” legionella risk assessment to comply with:
- Health & Safety at Work Act
- COSHH Regulations
- HSE ACoP L8 (Legionnaires’ disease)
Failure to carry out or maintain a compliant assessment can lead to enforcement action and serious health risks.
A properly conducted assessment ensures you:
- Protect staff, residents, visitors and the public
- Demonstrate legal compliance
- Reduce risk of outbreaks and liability
Healthcare Legionella Risk Assessments (HTM 04-01)
Healthcare environments present a significantly higher risk due to vulnerable occupants. We provide specialist healthcare legionella risk assessments in line with HTM 04-01.
This guidance sets out best practice for the design, operation and management of water systems in healthcare premises, with a strong focus on controlling legionella and other waterborne pathogens.
Our healthcare risk assessments are tailored for:
- NHS Trusts and hospitals
- Care homes and nursing homes
- GP surgeries and dental practices
- Clinics and specialist care facilities
We assess compliance with:
- HTM 04-01 Parts A, B & C

Healthcare assessments involve a more detailed and robust approach, including system design review, operational management, temperature control regimes and monitoring strategies required under HTM guidance.
They also support regulatory expectations (e.g. CQC) and help protect high-risk patients where exposure consequences are significantly greater.
